I havent had much time to work on the car lately but I have figured out a couple of things.
There is a control valve in the steering box that directs fluid to left or right, this is not working. The noise from the pump is bearings. Some of you have said the fluid could be running down the hoses from the pump to the steering box, this had me confused until I realised you guys have the pump and the steering box on the same side of the engine, we have right hand drive down here, and the hoses go up and down and around to get to the steering pump so I dont think thats possible. I have resigned myself to taking it all apart asap and doing the lot. I'll let you know how it goes.
Thanks for the MBSpares tip, John got me a very nice steering wheel, and I bought one of his CD manuals for the car and it seems pretty good,cost $AUS220 though thats about $US110, you guys probably buy them for $20.

Regards

John
